However, in this case, I think the problem is in OpenDBX or even in

So, a good start point would be if you can create a UnitTest of that so that
I can try to reproduce it and:

a) I can see what happens with other backends

b) I can ask Norbert (OpenDBX author) if he can reproduce it and if he as an
idea of how to fix it).
